Remove “this” callback in kotlin

Question

I\'m a bit kotlin newbie and I\'m trying to remove the callback instance inside the callback itself.

What I\'m trying to achieve it\'s something similar to the follo

Answer 1

There's also a workaround: wrap the reference to myCallback into a lambda passed to a function that calls it (e.g. run { ... }):

private val myCallback: SomeInterfaceType = SomeInterfaceType {
   if (it.something) {
        someObject.removeListener(run { myCallback })
   }
}

Answer 2

You need to use a full object expression syntax to refer to be able to refer to the instance itself:

private val myCallback = object: SomeInterfaceType() {
    override fun onSomeEvent() {
        if (it.something) {
            someObject.removeListener(this)
        }
    }
}
